Some patients may present with symptoms of relapsed disease after a previous cancer diagnosis. The relapse may be discovered by the patient or by surveillance in the post-treatment period.

Access to the best available therapies, including clinical trials, as well as treatment overseen by a multidisciplinary team, are crucial to achieving the best outcomes for anyone with relapsed or refractory disease.

There should be an immediate referral to a leukaemia multidisciplinary team specialist cancer service for all patients with suspected or confirmed relapse.
